Sandy Hook students return to school

A child sits on a Newtown bus leaving the new Sandy Hook Elementary School on the first day of classes in Monroe, Conn., Thursday, Jan. 3, 2013. Classes resumed Thursday for the students of the school where a gunman last month burst in and killed 20 children and six adults before killing himself. It was the second largest school shooting in the U.S. history. With their school still being treated as a crime scene, the more than 400 students of Sandy Hook Elementary School attended classes at the neighboring town's Chalk School.
